The majority of the radiotherapy are performed with linacs producing a uniformly intense electron-beam or X-ray beam of different energies. The linacs have the strong attraction of compactness, efficiency, reliability, moderate cost, and well-known technology. We developed and constructed the 6 MeV C-band linac which consists of a thermionic electron gun, a standing-wave accelerating column with the length of 450 mm, a 2.5 MW magnetron, a beam transport system, a beam collimation and monitoring

We design the gantry mounting our developed C-band linac isocentrically. In addition, the beam bending system and beam collimation are discussed to optimize the gantry space and to improve the beam performance. In this paper, we describe the designed radiotherapy machine including the gantry, a treatment couch and a control console, and present the study results.
